Wild radish is a notoriously hardy
survivor, with seeds known to survive in soil for 10 to 20
years.
However, a paper by Department of Agriculture and Food WA
researchers, Aik Cheam and Siew Lee, at the 2009
Grains Research and Development
Corporation (GRDC) supported WA Agribusiness Crop
Updates, had some useful tips for controlling it.
Controlling seed-set is very important and a single break year
will dramatically reduce seedbank enrichment.
Planting wheat has a big impact because of its competitiveness
and the availability of a good range of effective herbicides.
Finally, introducing a pasture phase will also significantly
reduce the seedbank because it allows green or brown manuring or
mechanical slashing to control radish seed production in spring. |
